ASPECTS OF USAGE OF ORGANIC OR AQUEOUS BINDERS BASED ON III OR IV GROUP ELEMENTS OXIDES IN THE PRODUCTION OF CERAMIC MOLDS FOR CHEMICALLY ACTIVE ALLOYS CASTING (review)

Abstract

The article considers the experience of using organic and aqueous binders based on silicon or aluminum oxides in the manufacturing of ceramic casting molds, and tendencies of world manufacturers in this industry to improve the quality, accuracy and operational reliability of cast products, especially critical parts made of titanium, intermetallic and heat-resistant alloys obtained by investment casting. The paper gives information on the results of studying physical and mechanical properties of ceramic molds and defect zone of the outer surface of castings made of various alloys.
